Follow The Capital - 7 Disruptive Theme ETFs
One research map for each critical layer of the next technology cycle
The largest fortunes are rarely built by predicting the next quarterly earnings beat.
They’re built by recognizing a new disruptive theme before the market fully understands it.
Every major wealth-creation cycle follows the same pattern.
A new disruptive technology emerges.
Capital pours into the infrastructure supporting it.
The companies controlling the bottlenecks create the most value.
That’s happening today.
AI is changing how intelligence is produced.
Robotics is bringing AI into the physical world.
Photonics is replacing copper as AI clusters demand faster data movement.
Power is becoming the limiting factor for AI growth.
Space is becoming communications, defense, and digital infrastructure.
Rare earths sit inside the motors, magnets, and electronics powering the next industrial revolution.
By the time these shifts become obvious, much of the easy money has already been made.
The goal isn’t to chase headlines.
It’s to identify where capital must flow next.
Why Invest in Thematic ETFs?
Disruptive themes are larger than any single company.
AI needs chips, memory, networking, cooling, power, and grid infrastructure.
Robotics needs processors, sensors, motors, joints, power electronics, and rare earth magnets.
The theme can succeed while an individual company fails.
Thematic ETFs spread that risk across the supply chain while providing access to foreign leaders, overlooked suppliers, and multiple potential winners.
They are also useful research tools.
Even without buying the fund, its holdings can reveal which companies control the most important parts of the ecosystem.
The Seven ETFs Built for the Next Decade
The next decade will be shaped by seven critical systems:
AI infrastructure, photonics, space, robotics, energy, grid infrastructure, and rare earths.
Each ETF below provides exposure to one essential layer of that buildout.
They were selected for:
Thematic purity
Holdings quality
Bottleneck exposure
Research value
The goal is not to own every fund.
It is to understand what each ETF owns, which part of the ecosystem it captures, and whether it offers better risk-adjusted exposure than selecting individual stocks.
SMH - VanEck Semiconductor ETF
The Foundation of AI Infrastructure
Every AI breakthrough begins with a semiconductor.
The winning AI model may change.
The companies supplying the chips are far less likely to.
$SMH provides broad exposure to the companies building the foundation of AI compute:
AI accelerators: Nvidia, AMD
Foundries: TSMC
Networking & custom silicon: Broadcom
Memory: Micron
Lithography: ASML
Chipmaking equipment: Applied Materials, Lam Research, KLA
Whether AI demand comes from OpenAI, Google, Meta, Microsoft, Amazon, or xAI, the semiconductor supply chain benefits.
Expense ratio: 0.35%
Best for: Core exposure to AI compute infrastructure
Key risk: Semiconductor-cycle volatility and concentration
Verdict: If you only want to own one AI infrastructure ETF, SMH is the benchmark.
DRAM - Roundhill Memory ETF
The AI Memory Bottleneck
AI models need more than processors.
They need HBM, DRAM, and NAND to feed data into accelerators and store massive datasets.
GPUs provide the compute. Memory keeps them fed.
$DRAM focuses on the companies supplying that memory stack:
HBM & DRAM: Micron, SK Hynix, Samsung
NAND: SanDisk, Kioxia
Enterprise storage: Western Digital, Seagate
As AI models become larger and inference scales, memory is becoming one of the industry’s most valuable bottlenecks.
Expense ratio: 0.65%
Best for: Focused exposure to AI memory and storage.
Main risk: Memory pricing cycles and short operating history.
DRAM is the purest ETF for investors who believe memory demand will continue to outpace traditional semiconductor growth.
LAZR - Tema Photonics & Optical ETF
The AI Data-Movement Bottleneck
GPUs create intelligence. Photonics moves it.
As AI clusters grow, copper is reaching its physical limits.
Optical networking delivers higher bandwidth with lower latency and lower power consumption.
$LAZR provides exposure across the optical ecosystem:
Optical components: Lumentum, Applied Optoelectronics
Compound semiconductors: AXT, Aixtron
Silicon Photonics: Tower Semiconductor
Fiber Infrastructure: Furukawa Electric
Testing equipment: Aehr Test Systems
The fund is actively managed in partnership with SemiAnalysis, one of the leading AI infrastructure research firms.
Now the part almost nobody has noticed.
The fund’s second-largest position is a private stake in Anthropic, roughly 12% of the portfolio.
You cannot buy Anthropic on any exchange. This is one of the only public wrappers that owns it.
Expense ratio: 0.75%
Best for: Focused exposure to optical networking and silicon photonics.
Main risk: Short operating history, high concentration, low assets, and private-company exposure.
LAZR is one of the few ETFs providing focused exposure to one of AI’s fastest-growing infrastructure layers.
NASA - Tema Space Innovators ETF
The Commercial Space Economy
Space is no longer just exploration.
It has become communications, defense, launch, and digital infrastructure.
$NASA owns companies across the space stack:
Launch: SpaceX, Rocket Lab, Firefly Aerospace
Satellite communications: AST SpaceMobile, Viasat, EchoStar
RF components: Filtronic
Lunar infrastructure: Intuitive Machines
The SpaceX position deserves attention. It sits near the top of the fund at over 13% through a pre-IPO SPV.
Expense ratio: 0.75%
Best for: Concentrated exposure to commercial space infrastructure
Main risk: High concentration, private-asset valuation risk, and space-company volatility.
NASA is one of the few ETFs offering great exposure to the rapidly expanding commercial space economy.
KOID - KraneShares Global Humanoid Robotics and Physical AI ETF
The Physical AI Supply Chain
Most investors focus on the robot makers. The bigger opportunity may be the companies supplying every robot.
$KOID provides exposure across the humanoid robotics supply chain:
AI and control: Nvidia, Monolithic Power Systems, Texas Instruments
Sensors and perception: Cognex, Sensata, Teledyne
Motors and actuation: Allient, Regal Rexnord, Nidec
Precision motion: THK, Harmonic Drive Systems, RBC Bearings
Rare earth materials: MP Materials, Lynas Rare Earths
Robot makers and integrators: UBTech, Symbotic
The fund tracks the full physical AI ecosystem rather than betting only on the company assembling the final robot.
It holds around 50 names, equal weighted, so no single winner dominates and no single failure sinks it.
Expense ratio: 0.69% net (0.79% gross)
Best for: Exposure to the complete humanoid robotics supply chain
Main risk: Early-stage industry and international exposure
KOID is the strongest ETF for investors who want exposure to the robotics supply chain instead of trying to predict the winning robot manufacturer.
